Internet not working and program crashes

I was on my computer and everything was working fine. Went to open a game which subsequently crashed, and repeated doing so. I then restarted my computer in the hope it would fix only to find a series of other programs crash on restart and the internet not working despite it saying it is connected. Run so far 3 anti-virus all of which could not find a problem. Internet explorer crashes when i try to open and google chrome comes up with error 137 (looked up solutions for that problem but to no avail). Really need help fixing this and i can give any more infomation needed. Tried disabling all my anti virus and firewall software but this did not help as well. At first I thought it was a virus but i'm not so sure now. Don't want to system restore but i can as a last resort.
